Thank you Fernando, thatís most helpful. I take it that this coat of arms for Spain dates to around the year 1700 when Philip, Duke of Anjou became king Philip V of Spain?

It seems plausible, although the Bourbons also reigned in Navarra in a prior century. But the flag not being a well succeeded example, i would remind that Jehan Lermite in his "Le passetemps", lists a number of Toledo smiths and his marks in a rather explicit manner, and mentions that Juan Martinez has marked his blades with a crowned fleur de liz before using other symbols. Lermite has been in Toledo around 1600.
